# Compute Features
|
||||
|
||||
The `compute` module provides statistical routines like descriptive
|
||||
statistics and correlation measures.
|
||||
The `compute` module hosts numerical routines for exploratory data analysis.
|
||||
It covers descriptive statistics, correlations, probability distributions and
|
||||
some basic inferential tests.
|
||||
|
||||
## Basic Statistics
|
||||
|
||||
```rust
|
||||
# extern crate rustframe;
|
||||
use rustframe::compute::stats::{mean, stddev};
|
||||
use rustframe::compute::stats::{mean, mean_vertical, stddev, median};
|
||||
use rustframe::matrix::Matrix;
|
||||
|
||||
let m = Matrix::from_vec(vec![1.0, 2.0, 3.0, 4.0], 2, 2);
|
||||
let mean_val = mean(&m);
|
||||
let std_val = stddev(&m);
|
||||
assert_eq!(mean(&m), 2.5);
|
||||
assert_eq!(stddev(&m), 1.118033988749895);
|
||||
assert_eq!(median(&m), 2.5);
|
||||
// column averages returned as 1 x n matrix
|
||||
let col_means = mean_vertical(&m);
|
||||
assert_eq!(col_means.data(), &[1.5, 3.5]);
|
||||
```
|
||||
|
||||
## Correlation
|
||||
|
||||
Correlation functions help measure linear relationships between datasets.
|
||||
|
||||
```rust
|
||||
# extern crate rustframe;
|
||||
use rustframe::compute::stats::pearson;
|
||||
use rustframe::compute::stats::{pearson, covariance};
|
||||
use rustframe::matrix::Matrix;
|
||||
|
||||
let x = Matrix::from_vec(vec![1.0, 2.0, 3.0, 4.0], 2, 2);
|
||||
let y = Matrix::from_vec(vec![2.0, 4.0, 6.0, 8.0], 2, 2);
|
||||
let corr = pearson(&x, &y);
|
||||
let cov = covariance(&x, &y);
|
||||
assert!((corr - 1.0).abs() < 1e-8);
|
||||
assert!((cov - 2.5).abs() < 1e-8);
|
||||
```
|
||||
|
||||
## Distributions
|
||||
|
||||
Probability distribution helpers are available for common PDFs and CDFs.
|
||||
|
||||
```rust
|
||||
# extern crate rustframe;
|
||||
use rustframe::compute::stats::distributions::normal_pdf;
|
||||
use rustframe::matrix::Matrix;
|
||||
|
||||
let x = Matrix::from_vec(vec![0.0, 1.0], 1, 2);
|
||||
let pdf = normal_pdf(x, 0.0, 1.0);
|
||||
assert_eq!(pdf.data().len(), 2);
|
||||

# Data Manipulation

|
||||
Rustframe's `Frame` type couples tabular data with
|

column labels and a typed row index. Frames expose a familiar API for loading
|
||||
data, selecting rows or columns and performing aggregations.

|
||||
|
||||
## Indexing Rows
|
||||
|
||||
Row labels can be integers, dates or a default range. Retrieving a row returns a
|
||||
view that lets you inspect values by column name or position.
|
||||
|
||||
```rust
|
||||
# extern crate rustframe;
|
||||
# extern crate chrono;
|
||||
use chrono::NaiveDate;
|
||||
use rustframe::frame::{Frame, RowIndex};
|
||||
use rustframe::matrix::Matrix;
|
||||
|
||||
let d = |y, m, d| NaiveDate::from_ymd_opt(y, m, d).unwrap();
|
||||
let data = Matrix::from_cols(vec![vec![1.0, 2.0], vec![3.0, 4.0]]);
|
||||
let index = RowIndex::Date(vec![d(2024, 1, 1), d(2024, 1, 2)]);
|
||||
let mut frame = Frame::new(data, vec!["A", "B"], Some(index));
|
||||
assert_eq!(frame.get_row_date(d(2024, 1, 2))["B"], 4.0);
|
||||
|
||||
// mutate by row key
|
||||
frame.get_row_date_mut(d(2024, 1, 1)).set_by_index(0, 9.0);
|
||||
assert_eq!(frame.get_row_date(d(2024, 1, 1))["A"], 9.0);
|
||||
```
|
||||
|
||||
## Column operations
|
||||
|
||||
Columns can be inserted, renamed, removed or reordered in place.
|
||||
|
||||
```rust
|
||||
# extern crate rustframe;
|
||||
use rustframe::frame::{Frame, RowIndex};
|
||||
use rustframe::matrix::Matrix;
|
||||
|
||||
let data = Matrix::from_cols(vec![vec![1.0, 2.0], vec![3.0, 4.0]]);
|
||||
let index = RowIndex::Int(vec![10, 20]);
|
||||
let frame = Frame::new(data, vec!["A", "B"], Some(index));
|
||||
assert_eq!(frame.get_row(20)["B"], 4.0);
|
||||
let data = Matrix::from_cols(vec![vec![1, 2], vec![3, 4]]);
|
||||
let mut frame = Frame::new(data, vec!["X", "Y"], Some(RowIndex::Range(0..2)));
|
||||
|
||||
frame.add_column("Z", vec![5, 6]);
|
||||
frame.rename("Y", "W");
|
||||
let removed = frame.delete_column("X");
|
||||
assert_eq!(removed, vec![1, 2]);
|
||||
frame.sort_columns();
|
||||
assert_eq!(frame.columns(), &["W", "Z"]);
|
||||
```
|
||||
|
||||
## Aggregations
|
||||
|
||||
Any numeric aggregation available on `Matrix` is forwarded to `Frame`.
|
||||
|
||||
```rust
|
||||
# extern crate rustframe;
|
||||
use rustframe::frame::Frame;
|
||||
use rustframe::matrix::{Matrix, SeriesOps};
|
||||
|
||||
let frame = Frame::new(Matrix::from_cols(vec![vec![1.0, 2.0]]), vec!["A"], None);
|
||||
assert_eq!(frame.sum_vertical(), vec![3.0]);
|
||||
let frame = Frame::new(Matrix::from_cols(vec![vec![1.0, 2.0], vec![3.0, 4.0]]), vec!["A", "B"], None);
|
||||
assert_eq!(frame.sum_vertical(), vec![3.0, 7.0]);
|
||||
assert_eq!(frame.sum_horizontal(), vec![4.0, 6.0]);

# Machine Learning
|
||||
|
||||
RustFrame ships with several algorithms:
|
||||
The `compute::models` module bundles several learning algorithms that operate on
|
||||
`Matrix` structures. These examples highlight the basic training and prediction
|
||||
APIs. For more end‑to‑end walkthroughs see the examples directory in the
|
||||
repository.
|
||||
|
||||
Currently implemented models include:
|
||||
|
||||
- Linear and logistic regression
|
||||
- K-means clustering
|
||||
- K‑means clustering
|
||||
- Principal component analysis (PCA)
|
||||
- Naive Bayes and dense neural networks
|
||||
- Gaussian Naive Bayes
|
||||
- Dense neural networks
